Filed Nov. 22, 1961, Ser. No. 154,174 2 Claims. ((31. 16-180) 1 This invention relates to a novel and useful jamb type hinge for overhead doors and relates primarily to a mounting assembly [for swingably mounting overhead doors and comprises improvements over my prior patents for Garage. Door Hinge, No. 2,712,670, and Spring Anchor Unit for Overhead Swinging Doors, 2,751,624.

In overhead swinging door structures it is sometimes desirable to provide a swinging door assembly having an extremely low overhead clearance. If an overhead door requires very low overhead clearance, it may be mounted in a manner so as to directly underlie the header of the door opening and require only A" clearance between the top of the door and the underside of the header. Accordingly, it is one of the main objects of this invention to provide a swinging overhead door mounting assembly which will enable an overhead door to be mounted for operation in a door opening requiring in the neighborhood of only A" overhead clearance between the top edge of the door and the underside of the header of the door opening.

A further important object of this invention is to provide a swinging overhead door mounting assembly in accordance with the'preceding object provided with elongated expansion spring means which may be readily adjusted in effective length and also laterally positioned at its end which is adapted to be connected to the overhead door in the plane in which the door moves from the closed to the open position whereby the swinging overhead door mounting assembly may be adapted to handle overhead doors of varying weight.

Another object of this invention is to provide a swinging overhead door mounting assembly in accordance with the preceding objects having incorporated therein adjustable stop means for limiting upward swinging movement of an overhead door whereby the door may be forwardly and downwardly inclined as desired and may be limited in its upward movement of travel.

Still another object of this invention is to provide a swinging overhead door mounting assembly including a pair 'of door attaching arms pivotally secured at one pair of corresponding ends to a mounting bracket which is attached to the door jamb and at the other pair of corresponding ends to a mounting member carried by the door and with means being provided for adjustably posi tioning the axis of rotation of one of said one pair of ends whereby the corresponding arm may be utilized to adjust the upward limit position of the overhead-swinging door.

A final object to be specifically enumerated herein is to provide a swinging overhead door mounting assembly in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to install so as to provide a device that Will be economically feasible, long lasting and rela tively trouble free in operation.

These together with other objects and advantages which Will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a fragmentary front elevational view taken from the inside of a building having a swinging overhead door mounted in an opening formed therein bymeans of the mounting assembly of the instant invention; FIGURE 2 is a side elevational view of the overhead door mounting assembly with the door shown in the open position in solid lines and alternate positions of the door and mounting assembly shown in phantom lines;

FIGURE 3 is an enlarged fragmentary vertical sectional view of a portion of the mounting member by which one end of the elongated expansion spring means is secured to the overhead door;

FIGURE 4 is an enlarged fragmentary horizontal sectional view taken substantially upon a plane passing immediately abovethe mounting bracket illustrated in FIG- URE 2 of the drawings and carried by the door jamb;

FIGURE 5 is an enlarged fragmentary vertical sectional view taken substantially upon a plane passing through the mounting member carried by the overhead door and showing the manner in which the adjacent end of the elongated expansion spring means may be adjustably positioned on the mounting member; and

FIGURE 6 is an exploded perspective view of the overhead door mounting assembly.

Referring more specifically to the drawings and to FIGURE 2 in particular, it will be seen that the numeral 10 designates a doorway formed in a wall 12 in which an overhead swinging door generally referred to by the reference numeral 14 is swingably mounted by means of the mounting assembly of the instant invention which is generally referred to by the reference numeral 16.

It will be noted that the mounting assembly 16 comprises a mounting bracket generally referred to by the reference numeral 18 which is secured to the door jamb defining the opening 10 in any convenient manner such as by fasteners 20. From FIGURE 6 of the drawings it has a generally L-shaped mounting plate referred to in general by the reference numeral34 secured thereto in any convenient manner such as by fasteners 36.

It will be noted that a pair of arms 38 and 40 have one pair of ends .pivotally secured to the mounting plate 18 and that the other pair of ends of the arms 38 and 40 are pivotally secured to the mounting plate 34 and the angle iron 32.

The other pair of ends of the arms 38 and 40 are secured to the angle iron 32 and the mounting plate 34 by means of fixed pivot fasteners 42 and 44 respectively and the ends of the arms 38 and 40 adjacent the mounting plate 18 are pivotally secured to the latter by means ofv pivot fasteners 46 and 48. The pivot fastener 46 is secured through an aperture 50 formed in the bight portion 22 whereas the pivot fastener 48 is secured through a rearwardly and upwardly inclined slot 52 formed in the bight portion 22. Accordingly, it may be seen that the axis of rotation of the corresponding end of the arm 40 may be adjustably positioned real-wardly and upwardly as desired.

The lower or forward end of the mounting plate 34 is provided with a laterally directed mounting flange portion 54 which has a [plurality of semi-spherical recesses 56 formed therein which open away from the pivot fasteners 42 and 44. One end of an expansion spring 58 is sewhose shank portion is secured through one of the apertures 62 opening through the recesses 56 by means of an adjusting nut 66 having a semi-spherical end portion 68 on one end snugly received in the corresponding recess 56.

With attention again directed to FIGURE 6 of the drawings it will be noted that an L-shaped mounting flange generally referred to by the reference numeral 70 is provided and includes a first apertured leg 72 which is secured in overlying relation to the leg 26 by meansof a tfastener 74 whose shank portionis received through the apertured leg 72 and the elongated slot 76 which is formed in and extends transversely of the leg 26. The leg 78 of the mounting flange 70 is provided with a stop pin 80 and the end of the expansion spring 58 remote tfrom the mounting flange 54 is secured to the stop pin 80 by means of an integral hooked end portion 82.

As can best be seen from FIGURES 4 and 6 of the drawings adjustable stop means generally referred to by the reference numeral 84 comprises a resilient cylindrical member 86 which is secured to the bight portion 22 by means of a shank type fastener 88 whose shank is secured through the elongated horizontally disposed slot 90 formed in the bight portion 22 and the cylindrical member 86 by means of a nut 92.

In operation, the pivot fastener 48 may be adjusted in the slot 52 for limiting upward swinging movement of the door 14 and the stop means 84 may be adjusted by means of the slot 90 to limit swinging movement of the arm 38. Additionally, the end of the expansion spring 58 remote from the mounting bracket 18 may be adjusted by means of the anchor nut 66 and also by engaging the hook 60 with a selected one of the recesses 56 formed in the mounting flange 54. The mounting flange 70 may be vertically adjusted relative to the leg 26 to increase the tension of the spring means 58 and also lateral positioning of the end of the spring 58 remote from the mounting bracket 18 may be effected by engaging the adjusting nut 66 in a selected one of the recesses 56. In this manner, the mounting assembly 16 may be adjusted to handle light, medium and heavy overhead doors.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
